People living in England enjoy better health than Americans, despite less investment in healthcare, research published in the US has revealed.
Across all ages, US residents tend to fare worse in terms of diabetes, high cholesterol and heart disease markers, data on over 100,000 people show.

It may be due to the UK's bigger drive on disease prevention, they say.
